【Abstract】 Serious frictional heating of a high-speed electric spindle is the main factor which influences and limits the rotating speed and machining accuracy of machining tools. This paper analyzes the thermal behaviour of high-speed electric spindle and its influence factors by testing. The methods used for improving thermal behaviour of high-speed spindle unit are suggested.更多还原
